Right.
Around the time this war was started, I had posted in this thread that if the Iranians fight as one nation, then they would come out ahead. And they have.
In this war, to make the Iranians capitulate would require only three routes:
1) Choking their economy until they imploded and had a civil war
2) Carpet bombing with heavy bombers for a long time and widespread area
3) Multiple nukes.
None of those options were practical. #1: Iran continued to have connections with the outside world and when Pakistan opened six trade routes to/from Iran, I understood that it was with the American blessings. #2: Huge risks of the American jets downed and prisoners taken and thus a repeat of Carter's Presidency. #3: Impossible, especially considering Iran was never a direct threat to America.
